NEW YORK (TheStreet) -- Apple ( AAPL) iOS users may spend more money on apps than Google ( GOOG) Android users, who prefer freebies , but there is still a chunk of iPhone apps available in the App Store for free.
Here are five that offer a wacky Wi-Fi twist. Blow Photo -- This gimmicky app turns on a five-second timer for the iPhone's camera before snapping a photo. Just blow at the screen. Yes, blow air on the screen. Amusing but that may tire after a while. A more useful feature is that you can edit photos on the fly -- add effects, brighten it up, crop and even draw on the image -- and then upload it over Wi-Fi to Dropbox, Evernote or other cloud-storage services.
One caveat: Blowing on the screen to set the camera's timer gives you just five seconds, so pose fast! Remote Snap !! -- Instead of using a self-timer for group photos, this app turns an iPhone into a remote control for well-timed shots. Remote Snap !! does require two iPhones (or iPads or an iPod Touch). One acts as the camera, the other is the remote. Cue the first camera phone and then get into position. The second phone turns into a remote that you press when everyone is picture perfect. The phones communicate over Wi-Fi and require typing in a code to connect. iNumKeyPad -- Thoughtful use of iPhone as a laptop's dedicated number key pad. To connect the two, both devices require some software and must be on the same network. Also, you may need to adjust the firewall to allow the app to link to the computer. Once linked, the iPhone-turned-number pad works immediately. Great for typing in loads of numbers. Developer MBPowerTools did address the main issue of repeated numbers. Just turn off "Repeat key" in the settings. Cup Phone -- This walkie-talkie-like app pays homage to the original childhood mode of communication: two cups and string. And while it seems like walkie-talkies are so outdated these days (um, this is a phone, after all), Cup Phone is handy and fun when two people are in the same building and don't want to yell ("Time for dinner"). It works over a local Wi-Fi network or Bluetooth. USB Sharp - Transfer multiple files to and from iPhone and PC with no extra software needed for PC. Nifty features are what make this app stand out -- zip a file on the fly, view a PDF and send the file straight to Dropbox or other cloud service. Not sure why USB is in the name when using Wi-Fi is so much more convenient. But what a timesaver when you don't want to muss with cables and iTunes. Caveat: Help page is in Chinese so if you don't know the language, you'll have to play around to see what else the app can really do.
